FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package hydrator-creator
Hydrator creator
The library is designed for hydrating objects through the class constructor. Additionally, with the help of expandable attributes, it is possible to add your own data extractors, modifiers, and validators. The attribute can be applied to the class or to parameters.
- Installation
- Usage
- Array of objects
- Alias for field
- Default value
- Required value for parameter
- Not empty validator
- Your own attributes
Installation
The package can be installed via composer:
Note: The current version of the package supports only PHP 8.1 +.
Usage
Result:
If the property is not of a scalar type, but a class of another object is allowed, it will also be automatically converted. If a class uses one parameter in the constructor, it will be automatically passed to the constructor without the need to specify the exact name. This allows for converting data into simple ValueObjects.
Result:
Array of objects
If you have an array of objects of a certain class, then you must specify the ArrayOfObjects attribute for it, passing it to which class you need to bring the elements.
Example:
Result
Alias for field
Various possible aliases can be set for the property, which will also be searched in the data source.
Default value
Using the DefaultValue attribute, you can set a default value for a parameter. You can also set default values using standard php syntax.
Result:
Required value for parameter
The attribute specifies whether a parameter value is required in the input data. The attribute can be applied to the class or to parameters.
Result:
Not empty validator
The NotEmpty attribute allows checking the completeness of arguments. It checks only if a value has been assigned to the argument, and it is not null. If the check fails, an exception will be thrown.
Result:
Your own attributes
To expand the functionality, you can write your own attributes that implement special interfaces depending on their purpose.
-
Sav\Hydrator\Attribute\ValueExtractoris used to change the search for a parameter value among input data. An example of such an attribute is Alias. -
\Sav\Hydrator\Attribute\ValueModifieris needed to transform the found value. An example could be the DefaultValue attribute. -
\Sav\Hydrator\Attribute\ValueValidatoris used to check extracted and modified data. An example is the NotEmpty attribute that validates empty values. \Sav\Hydrator\Attribute\ArrayMapis used to define the type of interpretation for values with a specific key. An example is the ArrayOfObjects attribute, which interprets each element of the array as a value of a specified class.
